Answer:

For the first one, the answer is x=32

For the second one, the answer is x= -16

Step-by-step explanation:

-120+11x=3x+136 (subtract 3x from both sides)

-120+8x=136 (add 120 to both sides)

8x=256 (divide both sides by 8)

x= 32

-7x-50=-2x+30 (add 2x to both sides)

-5x-50=30 (add 50 to both sides)

-5x=80(divide both sides by -5)

x= -16

Hope this helps!

Answer:

$\theta=54.2^\circ$

Step-by-step explanation:

Right Triangles

The ratios of the sides of a right triangle are called trigonometric ratios. Each acute angle has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides.

The tangent ratio is defined as:

$\displaystyle \tan\theta=\frac{\text{opposite side}}{\text{adjacent side}}$

The opposite side is 25 and the adjacent side is 18, thus:

$\displaystyle \tan\theta=\frac{25}{18}=1.389$

The angle is calculated by using the inverse tangent function:

$\theta=\arctan 1.389$

$\boxed{\theta=54.2^\circ}$
